Subject: RE: [External] SW8000419 Landmark Industrial Park Lot 9 ((301 Raleigh Street)
Good morning, Phil. Thank you, I am doing well and I hope you are, too.
As part of the certification and ownership change documents, you will need to include 2 sets of
revised plans -and a signed minor mod application form. The revised plans need to show the extent of
the proposed #57 stone area and a cross section detail of that #57 stone area with the 4" stone depth
and the location of the filter fabric labeled. Please also note on the detail that the #57 stone must be
washed and that no substitution for the #57 stone is allowed.
We'll process the ownership change first and the minor mod second, so when Mr. Miller completes
the minor mod application form, please make sure he completes it in the name of the LLC that will
receive this transferred permit, 301 Raleigh, LLC.
The renewal application should be submitted next year, 180 days before it expires. We can't accept a
renewal any sooner than 1 year before it expires. Submitting it sooner doesn't gain any additional
time — the next expiration date after the 2018 renewal will be September 20, 2026 regardless of
whether the renewal is submitted early or late.
I've got this in my rather large pile of projects to be inspected, hopefully early next week.

Hi Linda,
Hope you are well,
We are in receipt of your October 5, 2017 correspondence for the above site. After reviewing the letter and site we offer
the following:
1. It appears the owner has been parking on the green area beside the pond. We propose adding 4" No. 57 stone
on top of a filter fabric in the parking area.
2. We are obtaining measurements of the existing stormwater pipes and pond for certification purposes.
3. We will assist the owner with providing the correct paperwork.
Please let us know if this would address the three items form the letter.
Thank you,
Phil

2.t Provide two sets of sealed plans that show:
a. The layout of the existing BUA;
b. Existing drainage (i.e. BMPs, swales, pipes, buffer areas)
c. Sufficient existing contours and spot elevations
d. The layout of the proposed BUA, dimensioned
e. The proposed grading plan
f. Any proposed stormwater measures.
Calculations of the existing and proposed amount of BUA. These may be incorporated into the narrative if
desired.
4. Current impervious surfaces that are closer than 30' to surface waters and are requesting a redevelopment
exemption can not be any closer to the surface waters with the new redeveloped BUA then what was previously
established.
5. A request for an exemption can be reviewed under the Express or the Standard program. There is no fee under
the Standard program, but the timeline is longer than in Express.
If the information above is insufficient for you to submit this package to Express, please let us know and we will schedule
a scoping meeting. Once we receive and review the package and determine that the site is exempt, then you will
receive a written exemption for the area. This should be kept on file to show you are not required to get a stormwater
permit as long as you meet the definition of redevelopment for that area.
Let me know if you have any questions about the requirements to receive an exemption from the stormwater
permitting requirements.

Hi Mark
I've talked with Georgette Scott, Stormwater Supervisor for DEQ, about this project. She will be responding directly to
you about the meeting request that Ray sent in on the Port's behalf. Bottom line from State Stormwater's view, based

on whet Ray explained to me, is that there needs to be some measure of improvement in Stormwater Controls on the
site in order for Redevelopment to be pursued as a permitting option.
Let me know if there are ways I may assist.

Dear Mr. Miller:
Alan W. Klimek, P.E. Director
Division of Water Quality
The Wilmington Regional Office received an Express Stormwater Management Permit
Application for Landmark Industrial Park Lot 9 on September 10, 2004. A preliminary review of
that information has determined that the application is not complete. The following information
is needed to continue the stormwater review:
1. Please either delineate all wetlands on site, disturbed or undisturbed, or note on
the plans that none exist.
2. Please extend the bypass swales that catch the offsite runoff farther up the side
of the driveway pavement to avoid all possibility of that runoff entering the pond.
3. Please label the vegetated shelf area on the pond detail and specify the wetland
species to be planted on it.
4. Please dimension the building and the rear parking area including radii.
5. Please verify that the existing drainage system, which this pond will outlet into, is
-not ultimately draining to -a permitted state stormwater pond.
6. Please provide the street address of this property.
7. The provided forebay volume is only 15% of the permanent pool volume. Please
increase the volume so that it is within the range. of 18%-22%.

rootnotes:
1. When using the Division SAIDA tables, the correct SA/DA ratio for permanent pool sizing should be computed based upon the
actual impervious %and permanent pool depth. Linear interpolation should be employed to determine the correct value for non-
standard table entries.
2. In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90% TSS removal. The NCDENR BMP manual provides design tables for both 85% TSS removal and 90% TSS removal.
H. REQUIRED ITEMS C14ECKLIST
The following checklist outlines design requirements per the Stormwater Best Management Practices Manual
(N.C. Department of Environment,' Health and Natural Resources, February 1999) and Administrative Code

v-Vw'4�
a. The permanent pool depth is between 3 and 6 feet (required minimum of 3 feet).
b. The forebay volume is approximately equal to 20% of the total basin volume.
c. The temporary pool controls runoff from the design storm event.
d. The temporary pool draws down in 2 to 5 days.
e. If required, a 30 foot vegetative filter is provided at the outlet (include lion -erosive flow
calculations).
f The basin length to width ratio is greater than 3: 1.
g. The basin side slopes above the permanent pool are no steeper than 3: 1.
Ii. A submerged and vegetated perimeter shelf with a slope of 6: l or less (show detail).
i. Vegetative cover above the permanent pool elevation is specified.
j. A trash rack or similar device is provided for both the overflow and orifice.
k. A recorded drainage easement is provided for each basin including access to nearest right-
of-way.
1. If the basin is used for sediment and erosion control during construction, clean out of the
basin is specified to be performed prior to use as a wet detention basin
t4�et m. A mechanism is specified which will drain the basin for maintenance or an emergency.
III. WET DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT
The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the
vegetated filter if one is provided.
This system (check one) ❑ does X does not incorporate a vegetated filter at the outlet.
This system (check one) ❑ does X does not incorporate pretreatment other than a forebay.
Form S W U- l 02 Rev 3.99 Page 2 of 4

Maintenance activities shall be performed as follows:
1. After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general, condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs
within 2 to 5 days as designed.
2. Repair eroded areas immediately; re -seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed.
3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to
maintain proper functioning.
4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed
of in an appropriate manner and shall not be handled in a manner that will adversely impact water quality
(i.e. stockpiling near a wet detention basin or stream, etc.).
The measuring device used to determine the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.
When the permanent pool depth reads 4.875 feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads 2.25feet in the forebay, the sediment shall be removed.

5. Remove cattails and other indigenous wetland plants when they cover 50% of the basin surface. These
plants shall be encouraged to grow along the vegetated shelf and forebay berm.
6. If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment
through the emergency drain shall be minimized to the maximum extent possible.

Stormwater Narrative
Landmark Industrial Lot #9
New Hanover County, NC
Landmark Lot #9 is a -2.54 acre site which is undeveloped at this time. We
propose to construct a 12,600 sf office retail building with 29,420 sf of
asphalt parking and access with 1436 sf of concrete sidewalk and a possible
10,899 sf of future stone storage area. A wet detention pond is designed for
this site. The design will meet the states 1" requirement with 90% TSS
removal as well as the, City's4pre-post standard.
i
A 0.60 acre area from an off -site adjacent tract will also be accommodated
by the design of the pond. A maximum built -out area of 70% impervious
will be allowed for the off -site area draining to the pond. This pond will
outflow to an unknown tributary of the Cape Fear River classified C-SW.
